When air is supplied to the heat transfer medium 2-2 attached to the cooling surface, that is, to the cooling side, the air is cooled to supply the cold air to the apparatus including the cooling / heating module 10, 3) That is, when air is supplied to the heat generating side, the air is heated to supply the heated air to the apparatus.

At this time, when the temperature of the surface on the cooling side becomes lower than the saturation temperature on the humidifier line, moisture in the air condenses on the surface of the thermoelectric-element cooling surface and the surface of the cooling heat-transfer medium as condensation, thereby generating condensation. In this case, the flow path resistance on the cooling side gradually rises and the air supplied from the blower 1 is gradually supplied to the cooling side The amount of heat generated by the heat source can be reduced and more heat can be supplied to the heat source side. In the end, air can not be supplied to the cooling side but air can be supplied only to the heat side.

This condensation on the cooling side has a problem that the performance of the cooling / heating module 10 is significantly lowered.

Hereinafter, the present invention will be described in detail with reference to the embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 is a view for explaining a structure of a cooling / heating module according to an embodiment of the present invention. 3 is a view for explaining the structure of a cooling / heating module according to another embodiment of the present invention.

Referring to FIG. 2, the cooling / heating module 100 according to the embodiment of the present invention includes a first impeller 111, a second impeller 121, and a thermoelectric module 130. As used herein, an impeller may refer to an object designed to blow air in a desired direction. The impeller can move the fluid in a planned direction by applying kinetic energy to the fluid while rotating.

2, the cooling and heating module 100 includes a first driving unit 112 for driving the first impeller 111 and the first impeller 111, And a second blower 120 having a first blower 110 and a second driving device 122 for driving the second impeller 121 and the second impeller 121.

The thermoelectric module 130 includes a thermoelectric element 131 which is a set of thermoelectric elements disposed between a pair of insulating substrates and insulating substrates, heat transfer media 132 and 133 attached to respective surfaces of the thermoelectric element 131 ). Hereinafter, for convenience of description, it is assumed that the heat transfer medium 132 attached to the upper side of the heat sink 131 is defined as a heat transfer medium attached to the cooling surface, that is, the cooling side, The medium 133 is defined as a heat transfer medium attached to the heat generating surface, that is, a heat generating side. However, it will be readily apparent to one of ordinary skill in the art that the cooling and heating surfaces may be switched depending on the direction of the current.

The first impeller 111 sucks outside air and blows air to the cooling side 132 of the thermoelectric module 130. In addition, the second impeller 121 may suck outside air and blow air to the heat generation side 133 of the thermoelectric module 130.

That is, the cooling / heating module 100 according to the technical idea of the present invention is provided with at least two different impellers, and the air blown by each impeller can be blown only to the corresponding flow path.

For example, the first impeller 111 corresponds to the first flow path. The first flow path may be a path of air that is blown from the first impeller 111, passes through the cooling side 132, and is discharged through the first discharge port 140. The air blown by the first impeller 111 is only moved to the first flow path, and may not flow into the heat generating side 133, unlike the conventional technique described with reference to FIG.

And the second impeller 121 corresponds to the second flow path. The second flow path may be a path of air that is blown from the second impeller 121, passes through the heating side 133, and is discharged through the second outlet 150. Likewise, the air blown by the second impeller 121 may only flow to the second flow path, and may not flow into the cooling side 132.

As a result, according to the technical idea of the present invention, the air introduced from the outside can be discharged to the outside through the first flow path and the second flow path which are not communicated with each other.

The first impeller 111 may continuously apply a wind pressure of a predetermined level or more to the cooling side 132 and may cause the cooling side 132 to be cooled by the cooling side 132. In this case, The condensation generated on the surface may be discharged to the outside of the cooling side 132 (for example, the left side of the cooling side 132 in FIG. 2) by wind pressure.

The first flow path and the second flow path may include a first separating member 160 disposed between the first impeller 111 and the second impeller 121, the heat former 131, and the cooling side 132 And the second separating member 170 separating the air passing through the heat generating side 133 and the air passing through the heat generating side 133. [

The first separating member 160 connects one side of the case (housing) of the cooling and heating module 100 and the heat radiating part 131 and separates the upper side and the lower side of the first separating member 160 from each other .

The plurality of thermoelectric elements included in the thermoelectric part 131 may be protected by a predetermined sealing material. The sealing material may be disposed between the pair of insulating substrates so as to prevent foreign substances such as moisture from flowing into the thermoelectric elements (on the side of the P-type thermoelectric semiconductor elements and the N-type thermoelectric semiconductor elements) Can be applied along the perimeter of the thermoelectric elements between. The thermoelectric module coated with such a sealing material is described in detail in the Korean Registered Patent (Registration No. 10-1357731, "thermoelectric module having an improved sealing structure") of the present applicant, and thus a detailed description thereof will be omitted.

The second separating member 170 may separate the air passing through the cooling side 132 and the air passing through the heating side 133 from mixing. The second separating member 170 may be provided between the first outlet 140 and a discharge side (for example, the left side of the thermoelectric module 130 in FIG. 2) through which the air is discharged from the thermoelectric module 130.

At least a part of the second separating member 170 may be a moisture absorbing material capable of absorbing condensation discharged from the cooling side 132, that is, condensed water. The hygroscopic material may be formed of any material having a moisture absorption rate of a certain level or higher. For example, the hygroscopic material may be a nonwoven fabric, a moisture absorptive paper, or the like.

One surface (for example, an upper surface) of the hygroscopic material may be included in the first flow path. That is, the one surface may be exposed to the first flow path to absorb moisture discharged from the cooling side 132.

Further, the other surface (for example, lower surface) of the hygroscopic material may be included in the second flow path. That is, the other surface may be exposed to the second flow path. Since the second flow path is a path through which heated air passing through the heat generation side 133 moves, the hygroscopic material that absorbs moisture can be naturally dried through the heated air.

Therefore, when water is present for a long time, there is an effect that contamination, fungus generation, or odor can be solved. Also, it is possible to solve a problem that may occur when moisture is discharged to the outside of the cooling / heating module 100 (for example, pollution or malfunction of a predetermined device provided with the cooling / heating module 100).

In order to drive the first impeller 111 and the second impeller 121, at least one driving device (for example, a motor) may be provided. According to an embodiment of the present invention, as shown in FIG. 2, a first driving device 112 for driving the first impeller 111 and a second driving device 112 for driving the second impeller 121 Apparatus 122 may be provided.

That is, the first blower 110 and the second blower 120 may be included in the cooling / heating module 100, respectively. In this case, the driving speed (for example, rotational speed) of the first impeller 111 and the second impeller 121 can be controlled individually by the first driving device 112 and the second driving device 122 . As shown in FIG. 2, the first blower 110 may be included in the first flow path, and the second blower 120 may be included in the second flow path.

Also, the cooling / heating module 100 may be configured such that the first blower 110 for blowing air to the cooling side 132 can supply a relatively larger flow rate than the second blower 120. In order to supply a larger flow rate, the driving speed of the first driving device 112 is higher or the design parameter for determining the blowing intensity of the first impeller 111 is different from the design parameter of the second impeller 121 Can be designed.

For example, it is well known that various design variables such as the angle, shape, size, or thickness of the blades (blade) may exist, so detailed description will be omitted.

According to another embodiment of the present invention, the first impeller 111 and the second impeller 121 may be driven by one third driving device 113, as shown in FIG. In this case, the first flow path and the second flow path may be separated from each other so that the first flow path and the second flow path are not communicated. For this purpose, a predetermined separating material 160-1 surrounds the outer peripheral surface of the body of the third driving device 113, The impeller 111 and the second impeller 121 can be separated from each other.

The third driving device 113 is provided with a first rotating shaft 113-1 for transmitting rotational force to the first impeller 111 and a second rotating shaft 113-2 for transmitting rotational force to the second impeller 121 . At least one rotating device for individually rotating the first rotating shaft 113-1 and the second rotating shaft 113-2 is provided inside the body of the third driving device 113 so that the first rotating shaft 113-1 And the rotation speed of the second rotation shaft 113-2 may be separately controlled. According to another embodiment, the first rotary shaft 113-1 and the second rotary shaft 113-2 may be rotated at the same speed by one rotary device. In this case, at least one of design variables for determining the blowing intensity of the first impeller 111 and the second impeller 121 may be different from each other as described above, so that the cooling side 132 and the heating side 133 The incoming wind strength may be different from each other.

According to the technical idea of the present invention, a heat transfer medium is provided in which condensation formed on the cooling side 132 can be more easily discharged to the outside of the cooling side 132 (in the direction opposite to the impeller side) . This will be described with reference to FIG.

4 is a view for explaining an example of a heat transfer medium according to an embodiment of the present invention.

4, the heat transfer medium on the cooling side 132 may comprise a plurality of heat transfer fins (or heat transfer plates 132, 132-1) 4b, and the like. For example, as shown in FIG. 4A, the heat transfer fins may have a shape connected to each other, and each may have a separate shape as shown in FIG. 4B.

The air flowing into the cooling side 132 through the first impeller 111 can be cooled while moving between the heat transfer fins 132 and 132-1. In this case, when condensation, that is, a water droplet of a predetermined size, is formed on one surface of the specific heat transfer fin among the heat transfer fins 132 and 132-1, a part of the water droplet can be moved to the other surface of the specific heat transfer fin, 132, and 132-1, at least one through hole 133 may be formed.

When the through hole 133 is formed, the water droplet is divided into two sides of the specific heat transfer fin, so that a plurality of water droplets smaller than the size of the originally formed water droplet can be generated. The divided water droplets can be discharged to the outside of the cooling side 132 more easily by wind pressure.

The cooling / heating module 100 according to the embodiment of the present invention can be used in various devices having cooling and / or heating functions. According to one example, the seat can be used as a seat seat, a shield box, and the like, but is not limited thereto.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
